Using Prefix-Trees for Efficiently Computing Set Joins

  title={Using Prefix-Trees for Efficiently Computing Set Joins},
  author={Ravi Jampani and Vikram Pudi},
Joins on set-valued attributes (set joins) have numerous database applications. In this paper we propose PRETTI (PREfix Tree based seT joIn) – a suite of set join algorithms for containment, overlap and equality join predicates. Our algorithms use prefix trees and inverted indices. These structures are constructed on-the-fly if they are not already precomputed. This feature makes our algorithms usable for relations without indices and when joining intermediate results during join queries with… CONTINUE READING
